Atlas WeatherMaster Ice and Water Roof Underlayment

Description

The Atlas WeatherMaster Ice and Water Roof Underlayment is a self-adhesive underlayment which provides a secondary layer of waterproofing protection to prevent damage from ice and rain. Composed of a proprietary, SBS-modified asphalt, it provides excellent traction and protection from UV degradation and weathering. This Ice and Water Barrier has a high temperature stability and can be used in new construction or in a re-roofing application that requires a complete tear-off. Atlas manufacturers this roofing underlayment to be self-adhering and it does not require any special adhesives, equipment, or heat for installation.
